WILLIAM ENRIGHT, OF DETROIT, MICHIGAN.

VEHICLE-WHEEL.

To all whom 'it may concern:

Be it known that I, vWILLIAM ENRIGIIT, a citizen of the United States,residing at Detroit, county of Vayne, State of Michigan, have invented acertain new and useful Improvement in Vehicle-IVheels, and declare thefollowing to be a full, clear, and exact description of the same, suchas will enable others skilled in the art to which it pertains to makeand use the same, reference being had to the accompanying drawings,which form a part of this specication.

My invention relates to vehicle wheels, and the object of myimprovements is to secure an improved wheel having a resilient tire.

In the accompanying drawings,-Figure l, is an elevation of the wheelembodying my invention, a portion of the front plate being cut away andsome parts being shown in section. Fig. 2, is a section through thecenter of the wheel at right angles to its plane. Fig. 3, is a detailview of detached parts to illustrate the construction.

I form the main portion of the wheel of two plates, B, and B, joined bybolts or rivets b; these plates are preferably formed of sheet metal,and are secured to the hub A, by bolts or rivets, as indicated in Fig.2. Concentric with each of said plates is formed an annular portion D,semi-circular in cross section. Then the plates are joined together,these two annular portions form an annular tube, as indicated in Fig. 2.

C, are semi-cylindrical, radially extending portions of the plates B, B,which extend from the annular portions D, so that when the plates aresecured together the pairs of adjacent semi-cylindrical parts C, formradially extending cylinders or tubes, as indicated in Figs. l and 2.Between the two parts is placed a resilient pneumatic tube, E, andaround the outer and inner edge of said tubes are placed flexible stripsof leather, or other suitable material, M, N.

F, is a tube fitting and adapted to slide in each of the cylindersformed by adjacent parts, C, C.

H, is an extended head at one end of a tube F, and Gr, is an extendedhead at the other end of said tube. The head G, rests against the stripM, and is supported by the pneumatic tube E, and held at the outer endof its travel by the resiliency of said tube.

I), is a partition in the tube F.

Specification of Letters Patent.

Serial No. 407,578.

T, is a tire extending around the periphery of the wheel, its innerportion resting upon heads II of the tubes F.

I, is a wire, or bundle of wires, or other suitable devices, extendingparallel with the longitudinal axis of the tire T and embedded therein.

J, is a rod having an eye at its outer end, and screw threaded at itsinner end. The wires I, pass through the eyes of the bolts J, and theinner end of each of said bolts passes through the partition P, and issecured in place by a nut L, screwed upon the end of said bolt, andagainst the partition P, to hold the tire T, in place, and to hold eachof the tubes F, firmly against the tire. The strip M, is secured to thehead G, by rivets, m, m (Fig. 3).

The operation of the above described device is as follows: The tirebeing secured in place, air is forced into the tube E, to expand thesame and force the tubes F, toward or to the outer end of their travel,thus tightening and extending the tire T.

As the wheel rolls the tire T, is flattened or forced out of itscircular form locally, each of the tubes F, yielding, and when it ispassed the pressure point returning the tire to its normal shape, theinflated tube E, permitting this resilient action.

`What I claim is:

The combination of the disks B, B, having the annular portions D, D,semi-circular in cross section forming an annular tube, and the radialportions C, C, means for securing said disks together so that theportions C, C, register forming radially extended cylinders, a resilienttube E between the portions D, I), a tube F, adapted to reciprocate ineach of the cylinders C, C, a partition P, in the tube F, a resilienttire extending around the outside of the above mentioned elements andheld in extended positionA by the tubes F, a rod J, secured at its outerend to said tire and at its inner end passing through a hole in saidpartition, and a nut L upon the said rod, substantially as described.

In testimony whereof, I sign this specification in the presence of twowitnesses.
